Hi. I have read some complaints about this problem in the forums, but I can't remove it. Several weeks ago these 2 files start appearing in c:\ (where windows is installed). I delete both and then they reappear after some time. Now it seems autorun.inf is appearing in the other partition's root as well. All I did so far is a ccleaner run. Booted in safemode and run spybot 1.4. Have all windows updates installed (windows xp pro sp2) and running norton av corporate updated as well. I don't know if this is causing another issue I have here which I'll post later in windows OS forum, that summing up is a problem in which something stops some services (mainly windows audio service and network services) when the computer is ON for a while (sometimes hours, sometimes days), causing all windows audio to cease at all and networking too (mapping and disconnecting units for instance). Thanks for any help. If you want to see a HJT log I'll post later.
